The hook E maintains the combined clevises C, D, and F in a substantially horizontal pol sition, thereby niost effectuall y preventing the doubletree G and singletrees connected therewith from coming in contact with the heels of 'draft-animals hitched to said singletrees for' the purpose ofdrawing a plow.

We claim- The combination, vwith the series of clevises herein shown and described, of a pair of draftplatesconnected therewith by means of apin` 1f C2, and a double hook, E, for maintainiugsaid series of clevises in a substantially horizontal position, and thereby preventing a doubletree,
